B. Scapula
C. Astragalus
D. Cuboid

Answer

To solve the question "In rabbit, the bone present between the pubis and acetabulum is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify a specific bone in rabbits that is located between the pubis and the acetabulum.

2. **Review the Anatomy of the Rabbit's Pelvic Girdle**:
- In rabbits, the pelvic girdle is different from that of humans.
- In humans, the pelvic girdle consists of two coxal bones, each formed by the fusion of three bones: ischium, ilium, and pubis.

3. **Identify the Acetabulum**:
- The acetabulum is a cavity formed by the fusion of the ilium, ischium, and pubis in the pelvic girdle.
- It serves as the socket for the hip joint.

4. **Determine the Extra Bone in Rabbits**:
- Unlike humans, rabbits have an additional bone known as the cotyloid bone.
- The cotyloid bone is located in the pelvic girdle and is positioned between the pubis and the acetabulum.

5. **Evaluate the Other Options**:
- The options given are cotyloid, scapula, astragalus, and cuboid.
- Scapula is a shoulder blade and unrelated to the pelvic girdle.
- Astragalus and cuboid are tarsal bones related to the foot, not the pelvic girdle.

6. **Conclude the Answer**:
- The only bone that fits the description of being between the pubis and acetabulum in rabbits is the cotyloid bone.

### Final Answer:
The bone present between the pubis and acetabulum in rabbits is the **cotyloid bone**.
